WHAT TO DO

 You should try bandeja paisa in a traditional restaurant. If you eat local food, you discover authentic flavors. (Zero Conditional)

If you visit Medellín in August, you will experience the Flower Festival. (First Conditional)

You could go out at night in El Poblado. If you like dancing, you will have a great time learning salsa.

Debes explorar el metro porque está limpio y organizado. Los turistas no necesitan alquilar un coche porque el transporte público funciona muy bien.

I would like to go back and explore more natural parks in the future.
